So. Just because my interest was sparked, I decided to dig deeper into the $10 fee.. After a 7 day endeavor, I have found the following information, from 14 different people. One of the things with the $10 data fee, when they say Premium data, is that even though most are not in a 4g network, users of the HTC Evo will get priority data usage over all other cellular devices in the data calling pool. Long story short seeing as i'm hitting the hay soon is this. Basically, think of your cable internet connection. There are peak times, and non peak times. Peak times are when a lot of people are at home, logging on the net, and doing a bunch of data consumption. Everybody on a cable network shares a data pool. It's based on priority, but in a residential area, that priority is first come first serve. During the peak times, data speeds tend to slow down marginally, sometimes significantly depending on the network load. During non-peak times, your data is at it's fastest. 3G Data services tend to follow this same principal. With the Evo 4g, since customers are paying the $10 extra a month for the Evo, the Evo devices will get a priority on the data. This means that not only is your data cap lifted (the 5gig limit), but you are omitted from the data pool when it comes to data stream priority. This means that your Evo is like in a "non peak" time 24/7 because you're paying the premium data fee, meaning you're getting the fastest speeds possible at all times, even on a 3g network. Now, like I said, this comes from 14 different Sprint reps, all by different names, called at different times, and over a 7 day period. Some were from varying departments, but 10 of them were from the account management department. I don't know if this helps anybody get a little more insight, but I hope it does. I never had a problem with the $10 fee in the first place, but now I am even more comfortable with it.
